Abstract
Contactless reading device (10, 20) comprising transmission-reception means (11), and a power supply circuit (12) for the transmission-reception means (11), characterized in that the power supply circuit (12) comprises a magnetic contactor (13, 23) having a nominal open position preventing the powering of the transmission-reception means (11) and a closed position enabling the powering of the transmission-reception means (11), the magnetic contactor (13, 23) being in the closed position when an identification card (1) according to one of claims 1 to 3 nears the reading device (10, 20).
